Great idea that needs more support and attention: Solar Roadways has developed solar panels that can be used in place of pavement on roadways and parking lots, and in place of concrete on sidewalks, outdoor basketball courts, etc. They have LCDs and weight sensors built in to them so that they can be programmed to display any array of “paint” patterns desired, and they are able to sense weight on roads and warn drivers of upcoming obstacles. Amazing technology. The US DOT has awarded contracts for limited test applications on a stretch of road and on a parking lot. We need to see this happen nationwide.
